Besides, adding gelling agents (salts27 and glucose28) to a CNC coating solution poses a risk of interfering with the control of the self-assembly process of the CNCs. The interactions between the CNCs and the agents can increase the complexity of the CNCs’ self-assembly. Also, the ...
An increase in the use of gold potassium cyanide (GPC) for plating imitation jewellery has also contributed to the hefty rise, while the economic recovery in 2010 (albeit modest in some regions) has facilitated a rise in demand for May 2010 9 Gold Demand Trends plating salts used in luxury...

The sodium chloride concentration lies within the permitted concentration limit but it was unknown how far additional salts could provoke unwanted aggregation of the glyco-AuNPs. Upon exposure of glyco-AuNPs to LBB no change in the SPR absorbance and the UV-Vis spectra were observed over a time ...

AuNPs were prepared by reduction of gold salts using luteolin as a reducing and stabilizing agent. The prepared AuNPs were spherical in shape with an average diameter of 18 nm. F9 cells exposed to various concentrations of these AuNPs were not harmed, whereas cells exposed to RA exhibited a ...
